본문내용
50대 이후에는 중심동맥 경직(large artery stiffness)이 증가하고 반사파의 조기 도달 때문에 수축기혈압은 상승하고 확장기혈압은 하강하게 된다. 이 결과 수축기 혈압이 140mmHg이상이고 이완기 혈압이 90mmHg이하인 수축기 고혈압(isolated systolic hypertension)이 잘 생긴다.

A high resting pulse pressure is harmful and tends to accelerate the normal aging of body organs, particularly the heart, the brain and kidneys.

Normal
The pulse pressure increases with exercise due to increased stroke volume, healthy values being up to pulse pressures of about 100 mmHg, simultaneously as total peripheral resistance drops during exercise. In healthy individuals the pulse pressure will typically return to normal within about 10 minutes. For most individuals, during exercise, the systolic pressure progressively increases while the diastolic remains about the same.
